Definitions

  • the invention relates to a rotary cylinder lock with a cylinder housing and a plurality of tumbler pins, a rod-shaped extension being arranged at the outer end of at least one tumbler pin and penetrating a bore in the alarm state.
  • German patent specification 1 036 096 an electrical alarm device on rotary cylinder locks with pin tumblers is known, in which a current-carrying conductor is designed as a rigid contact pin projecting into one of the holes for the pin tumblers up to close to the head end of the tumbler pin, while a second current-carrying conductor is designed with its bare end extends radially into an annular groove running around the rotary cylinder so that the bare wire end does not touch the rotary cylinder.
  • the key and the rotary cylinder lock have a change which avoids that an alarm is triggered with the correct key when this key is inserted into the rotary cylinder lock.
  • alarm systems are known from numerous other publications, which can only be attached to a lock with increased time and effort. This workload is associated with increased costs and cannot be carried out by a layperson. Another disadvantage of these known alarm systems on rotary cylinder locks is that the locks can no longer be closed from the inside.
  • the object on which the invention is based is a rotary cylinder lock of the type mentioned Propose a way that enables an alarm to be triggered in a simple manner and that can also be retrofitted into a door by a layperson.
  • a hollow body is embedded in the cylinder housing, which has the holes on the side facing the tumbler pins and that each rod-shaped extension ends at the level of the associated hole when the correct key is inserted into the lock.
  • the rotary cylinder lock according to the invention is a compact unit that can be easily replaced by a layperson against the rotary cylinder lock present in a lock. It is not necessary to change the lock box or the door.
  • the external dimensions of the rotary cylinder lock according to the invention are the same as those of a normal rotary cylinder lock possible according to the DIN standard. Since the hollow body is embedded in the cylinder housing, the surface of the rotary cylinder lock according to the invention is identical to the surface of the rotary cylinder lock without an alarm device. The original external dimensions of the rotary cylinder lock have not been changed.
  • each tumbler pin consists of two parts, a core pin and a housing pin, which slide in cylindrical guides in the cylinder housing.
  • the locking pins are pressed down as far as possible by means of springs. If the correct key is inserted into the lock, the separation level between the core pin and the housing pin is at a height the outer surface of the cylinder core and the lock can be opened by turning the cylinder core.
  • the rod-shaped extensions are molded onto the tumbler pins in such a way that, with the correct key, they also terminate at a height. They end at the level of the associated hole in the hollow body. This means that the length of the guide arranged in the cylinder housing corresponds approximately to the total length of the housing pin and the rod-shaped extension.
  • At least one rod-shaped extension projects beyond the other rod-shaped extensions and is used to trigger an electrical alarm device. Due to the conditions, in particular the German DIN standards for the design of a locking cylinder with pin tumblers for door locks (DIN 18252), it is ensured that at least one rod-shaped extension penetrates the interior of the hollow body through the hole when the wrong key is inserted into a lock.
  • An advantage of the rotary cylinder lock according to the invention is that z. B. at a change of tenant, the rotary cylinder lock and thus the entire alarm device can be replaced and taken away by the tenant without damage or change to the lock box or the door.
  • Another commercially available rotary cylinder lock without alarm device can be installed again instead of the rotary cylinder lock according to the invention. This replacement can be carried out by a layperson, in which the main advantages compared to the known and conventional alarm devices.
  • the hollow body preferably consists of an insulating material and / or the inner sides of the hollow body have an insulating layer. This ensures that the hollow body is insulated on the inside and that no involuntary alarm is triggered.
  • a metal spring is attached in the hollow body, an electrical line leading from the metal spring to an electrical connection contact located on the outside of the lock.
  • at least one rod-shaped extension of a tumbler pin which passes through a bore in the hollow body touches the metal spring and a circuit is closed via the electrical line.
  • An electrical line which is connected to an electrical contact, is preferably attached to the cylinder body of the lock.
  • An alarm device can preferably be connected to the two electrical connection contacts.
  • This alarm device can be any electrical system which is suitable for triggering an alarm.
  • a bell or another device that triggers an acoustic noise can be connected to the connection contacts.
  • An optical display is also possible, e.g. B. a flashing light.
  • connection contacts are designed as plugs. In this simple manner, it is possible to insert and remove any alarm device in these connection contacts. In this way, it is easy for a layperson to connect an alarm device to the connection contacts.
  • each tumbler pin has a rod-shaped extension.
  • increased security is ensured since a rod-shaped extension is arranged on each tumbler pin.
  • the rotary cylinder lock according to the invention has the locking pins 2, 4, 6, 8, 10. These tumbler pins are formed in two parts. The exact parts are explained in detail using the example of the cylindrical pin 2.
  • the tumbler pin 2 consists of the core pin 52 and the housing pin 54. At the outer ends of each tumbler pin 2, 4, 6, 8 and 10, a rod-shaped extension 12, 14, 16, 18 and 20 is arranged. Above the tumbler pins 2, 4, 6, 8 and 10, the hollow body 22 is embedded in the cylinder housing 62, which has 30 bores 32, 34, 36, 38 and 40 on the side facing the locking pins 2, 4, 6, 8 and 10. The diameter of each hole 32, 34, 36, 38 and 40 is slightly larger than the diameter of the associated extensions 12, 14, 16, 18 and 20.
  • the diameter of the holes 32, 34, 36, 38 and 40 is also slightly smaller than the diameter of the cylindrical guides for the tumbler pins 2, 4, 6, 8 and 10 in the cylinder housing 62, so that the springs arranged above the tumbler pins 2, 4, 6, 8 and 10 find a sufficient hold.
  • the example of the locking pin 2 shows that the diameter b of the bore 32 is somewhat larger than the diameter a of the rod-shaped extension 12 of the locking pin 2.
  • the diameter c of the cylindrical guide 50 of the locking pin 2 is larger than the diameter b of the bore 32, so that the spring 60, which surrounds the rod-shaped extension 12, can be supported on the hollow body 22.
  • the hollow body 22 consists of an insulating material. However, it is also possible for the inner sides of the hollow body 22 to have an insulating layer.
  • a metal spring 24 is attached in the hollow body 22.
  • this metal spring is designed as a leaf spring.
  • the electrical line 26 leads from the metal spring 24 to the electrical connection contact 42 located on the outside of the lock.
  • the electrical line 28 is attached, which is connected to the electrical contact 44.
  • the correct key 46 is inserted into the rotary cylinder lock so that none of the rod-shaped extensions 12, 14, 16, 18 and 20 touches the metal spring 24 and no alarm is triggered via the contacts 42 and 44.
  • the length of the cylindrical guide 50 in the cylinder housing 62 of the locking pin 2 is approximately as long as the total length of the housing pin 54 and the rod-shaped extension 12.
  • the separation plane 64 between the core pin 52 and the housing pin 54 of the locking pin 2 touches the outer surface 66 of the cylinder core 68. This makes it possible to rotate the cylinder core 68 with the help of the correct key 46. If there is a wrong key in the rotary cylinder lock shown in FIG.
  • a key can also be inserted in the left part of the rotary cylinder lock shown, but it cannot trigger an alarm device.
  • the rotary cylinder lock shown in Figure 1 is installed in a door, the rotary cylinder lock can be closed at any time with a key in the left part.
  • the left part of the rotary cylinder lock is preferably actuated from the inside, whereas the right part represents the so-called external lock. If a wrong key is inserted from the outside into the rotary cylinder lock, a contact is triggered.
  • the connection contacts 42 and 44 can be designed, for example, as a plug into which any alarm device can be inserted.
  • a rod-shaped extension is arranged only on a tumbler.
  • the rotary cylinder lock according to the invention can be exchanged by a layperson for any rotary cylinder lock located in a door. No change is necessary on the door itself, nor is it necessary to change the correct key.
  • Such a rotary cylinder lock can, for. B. can also be easily removed from the door during a move and replaced with a known rotary cylinder lock without alarm device. Compared to known alarm systems, this shows Device on a particularly simple arrangement, so that there are no high costs, such as occur when installing and purchasing a known alarm system.
  • the rotary cylinder lock according to the invention can be operated from both sides, but the alarm is only triggered from one side.
